Vertical Jump Assessment: Understanding SJ, CMJ, and Drop Jump
How objective jump testing helps assess explosive power, reactive strength, and neuromuscular performance.
Vertical jump assessment goes far beyond measuring how high an athlete can jump. For coaches, sports scientists, and physical therapists, it provides valuable insights into lower-body power, force production, and the efficiency of the stretch-shortening cycle.
The Squat Jump (SJ), Countermovement Jump (CMJ), and Drop Jump (DJ) each assess different physical qualities, from pure concentric power to explosive and reactive strength.
Today, force plates enable professionals to analyze key metrics such as jump height, peak force, power, rate of force development, asymmetries, and Reactive Strength Index (RSI).
In this article, discover the key differences between SJ, CMJ, and DJ, the metrics to monitor, and how objective vertical jump assessment can support performance and rehabilitation.
